Hey Jeni,
So sorry to hear about your Dad!
Yeah, Ambien is such a weird drug. They claim it doesn't do much to relieve muscle pain, so one would figure that muscle pain wouldn't be too bad coming off it. But IMO, after seeing multiple doctors for a back injury followed by 2 years of nasty spasms with no relief, I finally had tried EVERYTHING... chiropractors, exercise, no exercise, rest, ice, heat, massage, spinal epidural, spinal nerve ablation, pain specialists and while they could point to things wrong with my back -- congenital disc disease, some arthritis, congenital facet joint disease, we all agreed it just shouldn't be causing me so much pain when I was quite mobile and active prior to this injury that by all rights should have healed.
Anyway, it took me 2 years and a boatload of different meds and procedures to figure out that FOR ME, the Ambien is so toxic and causes so much anxiety (and muscle tightening as a result) on a daily basis that the injury just can't heal. I liken it to a baseball pitcher "throwing out" his arm but continuing to pitch every day instead of letting it heal... even if it didn't need surgery... by abusing it that way it would never heal. Well, I base all of this on the fact that this spring I made it 42 days without Ambien or Vicodin. I only used ibuprofen. And, while my back didn't completely heal, it was slowly going in the right direction. I would say about 30% improvement vs. virtually 0% improvement in the 2 years prior. And then I went back on Ambien -- one 12.5mg pill per day max -- and within 2 months my back is just as locked up, painful and spasming as at its worst.
So that's my 2 cents -- for me, Ambien takes an injury or vulnerability I already have and makes it ache much worse. I've even have old root canals that have completely healed flare up for 2-3 weeks on this stuff but nothing's wrong with the teeth. One week one molar, another week an altogether different one on the other side. So, IMHO Ambien and Ambien withdrawal is fully capable of causing all kinds of weird aches and pains one wouldn't think would be related to a sleeping pill.
Sorry for the long diatribe... but I feel compelled to try to help or prevent anybody else from taking this drug any longer than they have to... it's just that nasty and I wouldn't wish my experience on anybody.
Best wishes, Jeni. ~Spoondog
